Now is about the time you might be panicking -- wondering if you've waited too long to plan a nice surprise for Valentine's Day. Fear not, there are still a couple of ways you can use your smartphone to order up a real-life gesture of romance, even at the last minute.

Poetry Store owner Silvi Alcivar writes poetry about whatever you ask her to in three minutes or less. Typed by hand, delivered in a glass jar, the Poetry Store is as low-tech as it gets, except that she's now writing on demand.

"We decided for Valentine's Day to have something really unique that really captures San Francisco's spirit," SixDoors founder and CEO Pascal Levy-Garboua said.

The on-demand shopping app is now offering on-demand poems written just for your valentine.

Order by 5 p.m. Thursday and the poem shows up Friday.

Now, if only you hadn't forgotten the flowers... Lucky for you, a new app sends flowers by bike within 90 minutes.

The service makes flowers the latest in a long line of things that can now magically appear at the touch of a smartphone. BloomThat founder Matthew Schwab wanted to do for flowers what Lyft and Uber did for calling a ride.

"We send a text message to you when the flowers are picked up, and then we notify you again via text message once those flowers are delivered," Schwab explained.

Of course, you won't need it -- your valentine will probably call once they're done showing them off.
